Lockheed-Martin F-16A Block 20
Fighting Falcon, 93-707 of the 21 FS of the 56 FW based at Luke
AFB, Arizona. It is owned by the Republic of China Air Force and
flown by a Taiwanese pilot training in the United States under
the Peace Phoenix program. Note the extended tail fairing.

Robert Coram has written a biography of John
Boyd, titled BOYD: The Fighter Pilot Who Changed the Art of
War. John Boyd served as an instructor at the Fighter
Weapons School at Nellis Air Force Base in the 1950s. He had a
standing bet that any pilot could put his fighter behind Boyd's
airplane, and Boyd would be behind the other pilot in less than
40 seconds or pay him $40. No pilot ever won that bet. Read my review of the book to see whether
you want to buy it from Amazon.com.
